WlNDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 449,562, dated March 31, 1891.

Application filed October 16, 1890. Serial No. 368,318. (No model.)

To all whom it may concern.-

Be itknown that I, LAVINIA H. MOOLELLAN, a citizen of the United States, residing at Bristol, in the county of Sullivan and State of lennessee, have invented certain new and useful Improvements in 'indow-Sashes; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window-sashes of that class known as sliding and swinging sashes, and it has for its object to provide a simple and improved device of this character embodying efficient means for locking the sash against lateral movement and which will serve to close the opening between the sash and guide-piece for the purpose of excluding cold air from the apartment.

A further object of the invention is to provide a window-sash of this character which will possess advantages in point of ineXpensiveness, durability, and ease of operation.

In the drawings, Figure 1 is a perspective View of a window and frame embodying my invent-ion. Fig. 2 is a transverse sectional view thereof. Fig. 3 is an enlarged trans verse sectional View of a part of the same. Fig. at is a detail perspective view illustrating the means for locking the retaining-strips.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the window-frame, which maybe of any suitable or well-known construction, embodying weight-boxes a a at either side, and the usual guide-strips a for the upper and lower sashes.

lVithin the spaces between the guide-strips pair of which being provided for each sash. The guide-pieces B project a considerable distance beyond the strips or molding a. and have sash-cords O 0 connected therewith, said cords passing over pulleys c 0, provided in the frame, and carry at their free ends balance-weights D D, working in the boxes to.

Between the opposing faces of each pair of guide-pieces B is disposed a sash E E, constituting the upper and lower sashes of the window. The sashes E are secured to the guidepieces by a pivot pin or bolt F F, disposed centrally at the side edges of the respective sash and adapt the latter to swing thereon, washers f f being interposed between the guide-pieces and the sashes and upon the pivot pins or bolts.

The opposing inner edges of the sashes and guide-pieces are each provided with a rabbet g. the opposing rabbets forming conjunctivelyv a longitudinal groove or recess G, extending from one end of the sash and adjacent guide-piece to the other. \Vithin each of the grooves or recesses thus formed is nor mally seated a movable strip G, of molding or other suitable material, designed to cover the space between the sashes and guide-pieces and exclude the outside air. The strips G are securedlongitudinally to the adjacent guide-pieces by hinges H H. The latter comprise short outer members it, countersunk in the guide-pieces and secured thereto, and elongated inner members h, countersunk and secured to the strips G, said members having their free ends 7L2 extended beyond the latter and over the adjacent portions of the respective sashes. The extended ends 72. of the hinges are countersunk in the sashes, the en tire outer surface of the hinges being thus flush with the several parts they traverse and form a neat and compact connection.

In practice the strips G are normally seated within the recesses provided therefor, and while in such position serve to both close the opening between the guide-strips and sashes and retain the latter against swinging, no matter what their vertical position may be.

For retaining the strips G in normal posi-' tion catches I are provided upon the sashes, consisting each of a tenon i, set in the inner face of the sash near the side edges thereof, and a head i, projecting at one side of the tenon and at right angles to the latter. The heads of the catches coincide wit-h and are designedto engage elongated slots 1, provided longitudinally in the extended ends 77. of the hinges. \Vhen a hinge is folded over its respective catch, the head of the latter is adapted to be turned until it engages the face of the hinge at either side of the slot, thus locking the strips in normal position.

The operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains. \Vhen the strips G are in locked position, the sashes may be adjusted to any vertical position without exposing any portion of the crack between the same and the guide-pieces, and the sash is further held rigid against any swinging or lateral movement. \Vhen it is desired to turn the sashes for the purpose of ventilation or cleansing the exterior thereof, the catches are first released from thehinges and the strips turned back upon their hinges to release the sashes.

I claim as my invention- 1. The combinatiomwith vertically-sliding guide-pieces and a window-sash pivotally suspended between the same, of a strip of molding or other material hinged to each of the guidepieces and adapted to be folded over the joint between the latter and the sash, said strips being carried by the guide-pieces through the movement of thelatter, substantially as and for the purpose set forth.

2. The combination, with vertically-sliding guide-pieces and a windo\ -sash pivotally suspended between the sam ,of a strip of molding or other material h nged to each of the guide-pieces and adapt .ed to cover the joint between the same and he sash, for the purpose described, and catches for locking said strips to the latter, substantially as set forth.

The combination,with vertically-sliding guide-pieces and a window-sash pi votally suspended between the same, said guide-pieces and sash having a rabbet at their inner op posing edges, forming conjunctively a longitudinal groove or recess at each side of the sash, of a strip hinged to each of the guidepieces and adapted to be received by said grooves or recesses, and means for locking the strips within the latter, substantially as set forth.

4. The combination, with vertically-sliding guide-pieces, a window-sash pivotally suspended between the same, and strips adapted to cover the joints between the guide-pieces and the sash, of hinges connecting the guidepieces and the strips and having extended inner members projecting over the edges of the sash, and catches for securing said extended members to the sash, substantially as set forth.

5. The combination, with vertically-sliding guide-pieees an da Window-sash pivotally suspended between the same, said guide-pieces and sash having a rabbet at their inner opposing edges, forming conjunctively a longitudinal groove or recess at each side of the sash, of strips adapted to be received by said grooves or recesses, hinges connecting the guide-pieces and strips and having extended inner members projecting over the side edges of the sash and provided with slots, and catches provided with fiat heads extending at one side, said heads being adapted to be received by the slots and engage the outer .face of the hinges to lock the strips in closed position, substantially as and for the purpose set forth.

In testimony whereof I aflix mysignature in presence of two witnesses.
